When you’re building a PC or upgrading your rig, there’s one component that’s very easy to miss, yet it’s essential for the best performance. A power supply unit (PSU) is the component that gives power to every single component inside of your PC. If you have a PSU that doesn’t give enough power, you can expect severely degraded performance – not to mention lots of errors.
The Nvidia GeForce RTX 3070 Ti is still a pretty powerful graphics card. Nvidia recommends at least 650W for this GPU, but it’s always a good idea to have more power just in case you want to upgrade in the future.
With that in mind, let’s take a look at the best PSUs for the RTX 3070 Ti graphics card.
